Even though I already gave you a definitive answer, I fwd your email to one of
the senior members of the Photoshop engineering team. He wrote:
We only read path information from AICB data on the clipboard (Adobe
Illustrator ClipBoard data format).
PDF, EPS - those come in as images to be rasterized
And of course, anything raster comes in as a raster image.
Which is EXACTLY what I told you.
Perhaps you can find some documentation on the AICB format in our SDKs or
online.

Subject: Re: [iText-questions] pdf graphics file questions
Hi,
Thanks, Mr. Rosenthol. I do appreciate your Sunday
early-morning response. By the way, I did know who you
are.
However, I still wish that there would be a way to make
Photoshop understand my curves as a vector graphics
file and allow me to paste as a Path. And I do not want to
use WMF/EMF, since I also want things to work on the Mac.
Could you please forward this question to an Adobe
Photoshop expert?
Thanks in advance! I really appreciate your help!
